Question

在python中导入模块时出现以下错误。我正在使用jupyter笔记本（python 2）。我通过互联网搜索但仍然无法弄清楚原因。任何帮助都会非常感激。

以下是代码：

import numpy as np
from pandas import Series,DataFrame
import pandas as pd
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-e4e9959b303a> in <module>()
----> 1 import numpy as np
  2 from pandas import Series,DataFrame
  3 import pandas as pd

 /Users/...filepath.../Python/data_analysis/numpy.pyc in <module>()
      17 
      18 import numpy as np
 ---> 19 from numpy.random import randn
      20 
      21 

      ImportError: No module named random

我尝试将import random添加到上面的代码中（在其他模块之前）并且它仍然会给出相同的错误。这可能是由于我系统上的gfortran版本？我有版本4.9.2

由于我没有完整的代码，只是尝试使用import语句。

如果我们按@John使用<table> <thead> <tr> <th>Name</th> <th colspan="3">Actions</th> </tr> </thead> <tbody> <% @customers.each do |customer| %> <tr> <td><%= customer.name %></td> <td><%= link_to 'Show', customer, remote: true %></td> <td><%= link_to 'Edit', edit_customer_path(customer) %></td> <td><%= link_to 'Destroy', customer, method: :delete, data: { confirm: 'Are you sure?' } %></td> </tr> <% end %> </tbody> </table> <br> <%= link_to 'New Customer', new_customer_path, class: "button", id: "new_customer" %> <div id="current_customer"> # This will will contain the partial </div> np
import numpy as np

我得到了 from np.random import randn
from np.random import randn

如果我从ImportError: No module named np.random

导入randn，我没有收到任何错误

numpy.random

它为我工作，输出如下，

import numpy as np
from numpy.random import randn
print "randn1= ", randn()

from numpy.random import rand
print "rand1= ", rand()

您也可以尝试直接使用randn1= 0.147667079884 rand1= 0.243935746205和np.random.randn()。

np.random.rand()

我明白了：
import numpy as np print "randn2= ", np.random.randn() print "rand2= ", np.random.rand()
randn2= -0.22571513741
